Given numbers are 436, 205, 634, 655

The list of prime factors of all numbers are

Prime factors of 436 are 2 x 2 x 109

Prime factors of 205 are 5 x 41

Prime factors of 634 are 2 x 317

Prime factors of 655 are 5 x 131

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 436, 205, 634, 655

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(436, 205) = 89380

GCD(436, 205) = ( 436 x 205 ) / 89380

= 436 / 205

= 436

Step2:

LCM(1, 634) = 634

GCD(1, 634) = ( 1 x 634 ) / 634

= 1 / 634

= 1

Step3:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

So, Greatest Common Divisor of 436, 205, 634, 655 is 1
